Given: ∆MNP, PM = 8 m∠P = 90°, m∠N = 58° Find: Perimeter of ∆MNP

Mathematics
1 answer:
VashaNatasha [74]3 years ago
8 0

Answer:

24.43 units to the nearest hundredth.

Step-by-step explanation:

We first need to find the lengths of sides PN and MN.

tan 58 = 8/PN

PN = 8 / tan58 = 5 .

sin 58 =  8 / MN

MN = 8 / sin 58 = 9.43.

So the perimeter = 8 + 5 + 9.43 = 22.43.

The expression that represent the area of the cut off part is 81π / 4

<h3>How to find area?</h3>

The area of the cut off part can be found as follows:

Area of a circle = πr²

where

  • r = radius

Therefore, the cut off part is like 1 / 4th of a circle.

Hence,

area of the cut off region = πr² / 4

r = 9 inches

area of the cut off region =  π9² / 4

area of the cut off region = 81π / 4

Bought three boxes totaling 151 book cost 50% more than the other two what was the price of the more expensive book 80 85 90 95
GenaCL600 [577]
Two cheaper books = x
more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90

The measure of one angle is six more than half the measure of another angle. If the angles are complementary, find both measures
Snowcat [4.5K]

Answer:

The measures of the two angles are 34° and 56°

Step-by-step explanation:

* Lets explain how to solve the problem

- The complementary angles are the angles whose the sum

  of their measures is 90°

- The measure of one angle is six more than half the measure

 of another angle

- Let the measure of the second angle angle is x

∵ The measure of the 2nd angle is x

∵ The measure of the first angle is 6 more than the half of the

  measure of the second angle

∴ The 1st angle is 6 + 1/2 x

∵ The two angles are complementary

∴ The sum of their measures is 90°

∴ x + (6 + 1/2 x) = 90

∴ (x + 1/2 x) + 6 = 90

∴ 3/2 x + 6 = 90

- Subtract 6 from both sides

∴ 3/2 x = 84

- Multiply both sides by

∴ 3x = 168

- Divide both sides by 3

∴ x = 56

∵ x is the measure of the 2nd angle

∴ The measure of the 2nd angle is 56°

∵ The measure of the 1st angle = 6 + 1/2 x

∵ x = 56

∴ The measure of the 1st angle = 6 + 1/2(56) = 34°

* The measures of the two angles are 34° and 56°
